I only sent the notifications today. In general, I always do this and will continue to do so.
As for the arena, it won't be possible for now. I don't have contact with the participants at the moment. And one of them sent a save file with a note that he will try to improve the result.
Thank you, I've already received it. It's a pity that we have to wait a long time for the arena. I wish everyone good luck!
